| | The user experience |
 | | A user model is typically described in terms of user objects, the behaviors and properties of those objects, and their interrelationships. |
 | | The difference is that OOP deals primarily with implementation aspects, while user models deal only with aspects that users are expected to experience through learning and use, such as the objects, or things, users employ to do their work. |
 | | The common user model consists of data and directories, represented as files and folders on a desktop, a clipboard along with cut/copy/paste actions, and programs, represented by Shortcuts and through data type associations. |
